The rise comes because the Nationwide Climate Service's Colorado Basin River Forecast Middle adjusted its snowmelt forecast to undertaking that 1.3 million acre-feet price of water will move towards Lake Powell over the following few months, 177% of the common.
Lake Mead, situated downstream from Lake Powell, can be anticipated to rise this 12 months, although, how a lot it rises is extra depending on how a lot water is launched from Lake Powell.

In the meantime, the Bureau of Reclamation additionally accredited a four-day managed launch from the Glen Canyon Dam as part of extra water it is sending downstream this month.
